3. Standard litre per minute - Wikipedia

   en.wikipedia.org/wiki/Standard_litre_per_minute

   The standard liter per minute (SLM or SLPM) is a unit of (molar or) mass flow rate of a gas at standard conditions for temperature and pressure (STP), which is most commonly practiced in the United States, whereas European practice revolves around the normal litre per minute (NLPM). [1]

4. Actual cubic feet per minute - Wikipedia

   en.wikipedia.org/wiki/Actual_cubic_feet_per_minute

   Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.

5. Air changes per hour - Wikipedia

   Q = Volumetric flow rate of air in cubic feet per minute (cfm) Vol = Space volume L × W × H, in cubic feet; In metric units = where: ACPH = number of air changes per hour; higher values correspond to more ventilation; Q = Volumetric flow rate of air in liters per second (L/s)

6. Thrust-specific fuel consumption - Wikipedia

   en.wikipedia.org/wiki/Thrust-specific_fuel...

   Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific.

7. Standard cubic centimetres per minute - Wikipedia

   en.wikipedia.org/wiki/Standard_cubic_centimetres...

   Yet another unit related to SCCM (and SLM) is the PCCM (and PLM) which stands for Perfect Cubic Centimeter per Minute (Perfect Litre per Minute). One PCCM is one SCCM when the gas is ideal. In other words, one PCCM is exactly the same as one SCCM if and only if Z n = 1 {\\displaystyle Z_{n}=1} in the above relationships.
